RALPH J. SHIPLEY, OF WATERBURY, CONNECTICUT, ASSIGNOR TO GEORGE W.MCGILL, OF RIVERDALE, NEW YORIL MACH N E FO R `MAKI NG PAPER-'FASTENERS.

SPECIFICATION forming part of Letters Patent No. 418,536, dated December31, 1889.

` Application iled October 22, 1889. Serial No. 327,815. (No model.)

ATo all' whom it may concern:

- eners ordinarily termed round-head, and

consisting of a T fastener formed from a single blank or strip of metal,and provided with a round metallic cap upset upon and firmly inclosingthe head of said fastener.

It is the purpose of my invention to provide automatic mechanism wherebythe manufacture of the fasteners and the attachment of the heads or capsthereto may be rapidly and automatically carried on, the metal blanksbeing fed to the forming-dies, the fastener bent to the required shapeand then fed to and inserted in an intermittently-revolving die, thecaps being fed to said die and placed upon or inclosing the head of thefastener, and the cap being upset upon the latter by pressure, wherebythe Ametal is turned over inward upon the head of the fastener andfirmly and permanently secured thereto.

` The invention consists to these ends in the several novel parts andcombination of parts hereinafter set forth, and then specificallypointed out and defined in the claims following' this specification. y

To enable others skilled in the art to practce'said invention, I will describe the same in detail, reference being had to the accoml panyingdrawings, in which-" i in Fig. 3. Fig. 5 is a detail view showing the'initial operation of the forming-dies. Fig. 6 is a detail View showingthe further action of said dies, initiating the bend of the blank. Fig.7 is a similar view showing the action of the bending-dies. Fig. 8 is asimilar view showing ling die. setting-dies, showing the fastener andcap in the final action of the bending-dies. Fig. 9 is a r similar Viewshowing the operation of the hammer-die and the completion of thefastener.

Fig. 10 is a plan View of the lower part of the 55 chute feeding thecaps, with the devices feed- `ing them to the die containingthefasteners. Fig. 11 is a plan view of the hopper containing 'the caps,the chute, and the clearing devices.

Fig. 12 is a detail elevation of the devices 6o giving intermittentmovement `to the revolv- Fig. 18 is a section of one of the upplace forthe action of the male die.

Following for convenience of description 65 the order of the successivesteps in the process of manufacture, as nearly as it is possible to doso, the reference-numeral 1 designates the bed-plate of the machine,which maybe supported on legs 2. Projecting from 7c one side of thisbed-plate is a lateral extension 3, upon which is erected a hopper 4,having an opening 5 of a size adapted to receive and permit the descentof a stack or pile of blanks `consisting of narrow strips of thin metalof suitable length, the hopper being supplied by a cob 6 mounted thereonin the usual manner. y

The hopper 4 is sustained upon a vshelf or supporting-plate 7, Fig. 3,rigidly mounted on 8a the extension 3, and beneath this shelf arearranged slideways 8, withinwhich is mounted a carriage 9, having anextended fiat surface. This carriage is providedwith a thin feed bladeor plate 10, attached by one end to a block 12, to bring it into theplane of the bottom of the hopper 4, between which and the surface ofthe shelf 7 the plate .reciprocates in a space just sufficient to permitthe passage of a single blank lying iiatupon its face. 9o

The carriage is reciprocated by a pitman 13, connected with a wrist-pinon a wheel 14,

`carried by a shaft 15, mounted in bearings 16,

Fig. 4, on the lateral extension 3. At each forward movement of thefeed-blade the car- 95 riage 9. Depending from this carriage is a roosocket 17, in which lies a carrier 18, having a metal pin 19 projectingfrom its upper end and passing lthrough an opening in t-he carriage 9.The carrier 1S, while reciprocating with the carriage 9, has also avertical reciprocation of its own, whereby it is raised and causes thepin 19 to project above the surface of the carriage a distance aboutequal to the width of the blank. This pin is raised and lowered by alever 20, fulcrulned upon a dropbearing 21 beneath the carriage andhaving a friction-roll at its end running on a cam 22 011 the shaft 15.The end of this lever is provided with a long slot 23, engaging a studprojecting from the carrier 1S. The pin 19 rises as the movement of thecarriage 9 carries it past the rear of the hopper, whereby the blankfalls on the carriage between the hopper and the pin. As the carriage 9recedes, the blank is carried with it until its edge is brought againstthe vertical faces of two separable dies 24, which are pressed togetherby powerfulsprings 25, Fig. 4. Thepin 19 reciprocates in the line of themeeting faces of these dies, and their edges or angles are beveled offor rounded at 26, giving an entrance for the pin between said dies.These dies lie directly underneath the hopper 4 and move in wayssupported by the shelf 7. As the blank is brought against them, the pin19 impinges upon the middle or near portion of the blank, turning thelatter upon its edge, and bringing one iiat face against the verticaledges of the dies 24, while the other face lies against the The furthermovement of the carriage 9 draws the pin into the recess formed by therounded angles 2G of the dies, part-ly bending the blank, as shown inFig. G. It then passes onward, drawing the blank wholly between thedies, as shown in Fig. 7, and finally carrying the pin and the bentportion of the blank through and out of the dies, whereon the latterclose, as shown in Fig. 8, forcing the prongs together. The pin 19 isnow withdrawn, and a hammer-die 27, reciprocated by the pitman 13, isbrought against the circular loop formed by the pin, as shown in Fig. 9,attening said loop and completing the fastener.

The carriage which has gone forward again recedes, carrying anotherblank through the dies and thereby forcing the completed fastener outand bringing it into the path of a slide-bar 2S. having a recess 29 inone an gle, which receives one-half the head of the fastener, while theprongs lie fiat against its end. This slide pushes the fastener to achute 30, in which it descendsto and rests upon aslideplate 31, arrangedin a way 32 in a bracketblock 33, mounted on the main frame or bedplateand lying underneath the table or extension 3. This slide is thrownforward by a spring 34 and retracted by a lever 35, fulcrume'd on a lug3G and opera'ted by a cam 37, carried by a shaft 38, journaled partlyupon standards rising from the main frame and .from its axis.

partly on a bracket 39, projecting from said standard.

\Vith the slide-plate 31 is coupled a second and longer slide-plate 40,lying below and separated from the slide-plate 31 by means of a rigidplate 41. Both these slides are coupled to a head 42, with which aguide-bar 43 connects, sliding in the bracket-block and connected by apin to the slotted end of the lever 35.

As the fastener sinks to the bottom of the chute 30, it lies on t-heslide-plate 31 until, as the latter recedes, it is dropped upon theintermediate plate 4l. The forward movement ofthe slide then pushes it,prongs first, until it passes oit the plate 41 and falls upon theslide-plate 40. The retrograde movement of the latter brings the head ofthe fastener against the end of the stationary plate 41, whereby it isswept off the long slide-plate 40 and drops upon the oor of the recess32. At the next forward movement of the slide 40 the fastener is driven,prongs foremost, through the passage-way in the bracket-block '33, inwhich said slide moves, and passes out at the end of the same, itsprongs or feet being received in suitable cavities in a rotary die-block43, so arranged that its periphery, in which said cavities are formed,is brought close to the end of the bracket-block 33 and opposite theopening from which'thc blank is fed.

The rotary die-block 43 is journaled beneath the bed-plate 1.. Itconsists of a largev block of metal carrying a series of dies 45, allarranged radially withrespect to the shaft of the die-block and at thesame distance Each of the dies 45 contains an aperture 46, adapted toreceive thc feet or prongs of the fastener as it is driven by theslide-plate 41, and is provided with a circular upsetting die 47 (shownin cross-section in Fig. 13) and adapted to receive the crosshead of thefastener. The dic-block is mounted on a shaft 48, Fig. 2, supported inbearings 49, and with which the block is rigid.

rThis shaft projects from one side of the dielthrough a drop-bracket 51,and havinga point vwhich enters a seat in theface of the block. Ajam-nut 52 holds the stud-bearing at any point to which it may beadjusted.

The shaft 48, carrying the die-block, is rotated intermittently by meansof a doublevarmed lever 53, loosely mounted on the end of the shaft 4Sand carrying spring-pressed vpawls 54, which engage a ratchet 55, rigidon said shaft. The lever 53 is reciprocated by a slide 5G, moving inways 57 and connected to the lever by a turn-buckle 58. The slide isactuated by a cam-arm 59, having upon its end a friction-roll 60,'lyingin a cam-race G1,

,formed in a wheel G2. After each feed movement the die-block is held bya detent-bar 63,

the point of which enters openings 64 in the face of the block. This baris operated in IOO IIO

one direction by a spring 65 and in the other by a cani-lever 6G, havinga ,roll 67, running on a cam 68 on the same shaft with the wheel 62, thespring effecting the locking engage# ment -andthe lever releasing thebar.

Arranged above the bed-plate 1 is a chute 68, its delivery end beingplaced a little to one lside of the die-block 43, Fig. 10. This chutecontains a passage 69, of such size and shape as to permit the passageof a single line of the caps, which consist of cup-shaped bodies of thinmetal, which pass down within the channel 69, resting on ytheir openends, the overhanging edges of the chute confining them in the channel69 and preventing them from escaping. rlhe series of caps contained inthe chute press the lower cap ont of the channel, whence it passes undera light leaf.`

spring 7 O` and against a shoulder or plate 7 Oa, by which it isstopped. A feed-bar 71 then advances and pushes the cap from beneath thespring into the upsetting-die 47, where it rests upon its edges,surrounding the head of the fastener. A male die or punch 72 thenIdescends upon the cap, whose edges are by the peculiar formation of theupsetting-die caused to curl inward, passing beneath the ends of thecross-head of the fastener and being securely attached thereto. The maledie is carried by a sliding head 7 3, moving in a standard 7 4 andactuated by a toggle-lever 75, which in turn is operated by a pitinan76, connected to a crank on the shaft 38.

The caps are placed in anyv suitable number in a hopper-barrel 77,mounted on an inclined axis 78, to which revolution is iinparted by abelt 79, running over a pulley on the inclined shaft of the hopper, anddriven by a pulley 8l on the shaft 38. The hopper or drum 77 consists ofa cylindrical recepta` cle revolving upon a fiat inclined stationaryshelf 82, a ring 83 being mounted on said shelf between the latter andthe drum. In the4 ring 83 is forinedan opening 84, of a size adapted topermit the escape of one cap at a time, provided said cap issues throughsaid opening uponits open end. If turned upon its side or upon itsclosed end, it will stick in -the opening, the latter being arrangedoppo- -site the entrance to the chute 68.. In order the revolution ofthe drum the leaf-spring is drawn between the drum and the curved arm ofthe bell-crank, which is thrown by said spring away from the barrel,projecting the slide inward andclearing the opening. Upon the interiorof the drum are mounted'brushes 90, which agitate the caps and assist inpresenting them to the escape-opening 84.

The stroke of lthe male` die 72 is adjusted by means of a stem 9i,passed through the top of the standard 74 and connected to the head 92,which is pivoted to one arm of the toggle-lever 75. Jain-nuts 93 and anadjusting-nut 94, turned on fthe stem 91, provide means for theadjustment.
